.SHORT TERM...
(Today through Friday Night)
Issued at 355 AM CDT Thu Apr 25 2024

Latest sfc observations show that a stationary bndry was situated
roughly along a line from KMEZ to KLLQ. Sfc dewpoints were well into
the 60s south of the fnt, with 50s common to the north. Sctd
showers/ few storms have been forming over the last few hrs north
of the fnt as the first in a series of upper impulses apchs the
FA fm the west.

The aforementioned front wl slowly lift back to the north as a warm
fnt later today and tngt as a strengthening sfc low over the eastern
Rockies lifts to the northeast. Convective chcs today and tngt wl be
concentrated mainly north of the warm fnt. Cannot rule out a few sub-
severe hailers today, but organized severe wx is not expected.

This scenario wl also produce quite the range in high temps today
acrs the FA. Far southern AR wl top out in the lower 80s, with parts
of north AR struggling to reach to the 60 degree mark.

The bndry is expected to lift north of AR by Fri mrng, with a warm
and humid airmass firmly in place. Initially, PoPs early Fri wl be
confined to parts of northern and western AR, assocd with overnight
convection movg in fm eastern OK.

Conds are expected to destabilize further to the east Fri aftn,
which could lead to additional strong or severe storm formation. The
extent of the severe potential rmns uncertain as much depends how
convection earlier in the day evolves. Lingering cloud cover is a
primary factor in this case. Overall threat of severe wx wl diminish
later Fri ngt, along with a gradual decrease in precip coverage as
the main upper support begins to shift north of the region.

.LONG TERM...
(Saturday through Wednesday)
Issued at 355 AM CDT Thu Apr 25 2024

An unsettled weather pattern will be present most of the long-term
forecast period of Saturday through Tuesday. In the upper lvls, a
series of closed lows and SWTs will approach the region. In tandem
at the sfc, a series of low pressure systems will remain in the
Central Plains region of the CONUS with their attendant southward
extending cold front and dryline in cohesion with a warm front
and/or stationary boundary well north of the state that will allow
for a large warm sector to open up across the Southern Plains into
the Mid-South regions of the CONUS. At the current time, a slight
risk of severe weather will be possible across portions of Arkansas
on Saturday and Sunday as all modes of severe weather will be
possible. Expect several rounds of rain and thunderstorms across the
CWA through Wednesday when the trof axis finally pushes over the Mid-
South region of the CONUS and the sfc cold front finally moves
across the state of Arkansas on Monday, but becomes a stationary
front stalled out across the southern part of the state on Tuesday
keeping POP chances in the forecast across the CWA through Tuesday.
Into Wednesday, the stationary boundary pushes well south of the
state as a cold front and a sfc high pressure center placed across
the Tennessee River Valley will bring dry conditions back to the
much of the Natural State for part of the day with considerably
lower POP chances.

All modes of severe weather will be possible over the days of
Saturday and with a greater chance of severe weather across the CWA
on Sunday. Saturday severe weather chances will be reserved to
northwestern Arkansas and Sunday severe weather chances will be more
widespread across Arkansas. Note subsequent future forecast packages
as the threats this weekend become clearer and will present a
greater confidence overall in future discussion; however,
preparations for severe weather need to be made across the CWA in
respect to all modes of severe weather including flash flooding.

A threat that needs to be also addressed is the possibility of
excessive rainfall over the period of Saturday and Sunday in which
localized flash flooding will be possible across the state and CWA.
The threat itself needs to be treated in the same capacity of the
threat of the traditional all modes of severe weather associated
with a few tornadoes, severe wind gusts, and large hail.

Temperatures over this period will be slightly above normal with
respect to both low and high temperatures over this period compared
to climatological normals.

Warm fnt wl be slowly working to the north over the FA thru the
PD. Moisture wl cont to incrs along and north of the bndry, with
mainly lower end VFR ceilings expected thru daybreak. Sctd
showers/storms wl dvlp on Thu, with MVFR/VFR conds bcmg common
over northern and central AR. Eventually conds wl lower to IFR
later Thu aftn and evening.
